Regenerative air brake module

Patent Number: 8465107
Publication Date: 2013-06-18
Inventor:

An air braking system for a vehicle blends regenerative and foundation braking during low deceleration conditions in an effective and controlled manner. The braking system also includes a mechanical override that bypasses system electronics in response to an aggressive brake request such that treadle circuit pressure is sent directly to a brake relay circuit to actuate vehicle ...

Electromechanical brake force booster

Patent Number: 8459753
Publication Date: 2013-06-11
Inventor:

The invention relates to an electromechanical brake force booster for a hydraulic vehicle brake system. The invention proposes that the brake force booster be formed with two restoring springs, one of which acts on an electromechanical actuator and the other of which restoring springs acts on a pedal rod. In the event of failure of the electromechanical actuator, only the other spring, which preferably has a relatively low spring force, must be compressed using muscle force. The force loss ...

Redundant hardware architecture for the power stage of the braking system of a vehicle in which each of the wheels are connected to at least one rotary electrical machine

Patent Number: 8449049
Publication Date: 2013-05-28
Inventors: ; ;

An electric braking system for a vehicle includes first and second sub-systems connected to each other by an electric line. The first sub-system, which includes a first dissipation device, controls braking in a first wheel set. The second sub-system, which includes a second dissipation device, controls braking in a second wheel set different from the first wheel set. The electric line is arranged such that:

- if the first dissipation device becomes ...

Redundant hardware architecture for the low-voltage power supply stage of the braking system of a vehicle in which each of the wheels is connected to at least one rotary electric machine

Patent Number: 8449048
Publication Date: 2013-05-28
Inventors: ; ;

An electric braking system is provided for a road vehicle that includes at least two wheels (1) each connected for rotation to at least one rotary electric machine (2), and one electronic wheel control module (23) controlling an electric machine of a corresponding wheel, with each electronic control module enabling a control torque of determined amplitude and sign to be imparted selectively to a corresponding wheel. The electric braking system includes at least two ...

Braking system for motor vehicles

Patent Number: 8449047
Publication Date: 2013-05-28
Inventors: ;

A brake system with a master cylinder, a first piston which is coupled to a brake pedal via a push rod transmitting actuating forces, a second piston which can be actuated by the first piston and which can be brought into force-transmitting connection to a third piston, via which the master cylinder is actuated, at least one elastic element which forms a pedal travel simulator which, in the “brake-by-wire” operating mode, gives the vehicle driver a pleasant pedal sensation, an ...

Two-stage master brake cylinder

Patent Number: 8449046
Publication Date: 2013-05-28
Inventor:

A two stage master brake cylinder uses a primary and secondary piston to displace an initial large volume of hydraulic fluid during a first stage and a second stage that continues brake actuation by displacing a reduced volume of hydraulic fluid determined by the secondary piston. A by-pass control valve is adjustable to vary transition from the first stage to the second ...
